After lurking for YEARS, I thought I would revive this thread to both introduce myself and provide some valuable info right from the start.
I recently purchased a pristine '06 in Autumn Gold Elise. Bone stock. One owner. Sport, touring, hardtop, starshield. Less than 7k miles on the clock. It's pretty darn sweet.
Anyway, I also just ponied up to get the provenance from Lotus because I wanted to know, once and for all, about the rarity of AG.
Based on the draft Andy just sent me, here's the official intel:
For the US market, AG was only offered in 2006. Never released on US/Canadian Exige.
2nd rarest color next to aubergine purple out of the 21 colors available.
For the US market, there were actually 10
AG elises. 8 of them had black interiors. 1 other exactly like mine (options and black interior).
For the Canadian market, there were 2 AG Elises. One black interior, one magnolia.
It was going to be too time consuming for him to research all the other markets beyond North America. But he mentioned that there were two paint trial UK 2005 Elise 111Rs made that were Lotus company cars.
I know some of this had already been figured out, but hopefully this helps anyone looking for more info on AG and general color rarity for 2006.
